' METHOD OF FORGING OX-SHOES.

$PECIFICATION' forming part of Letters Patent No. 314,190, dated March17, 1885.

Application filed August 21, 1884. (No model.)

To all whont it may concern:

Be it known'that I, WILLIAM Pearson, of Plantsville, in the county ofHartford, and in the State of Connecticut, have invented certain new anduseful I Improvements in the Manufacture of Ox-Shoes; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, in which-Figure 1 is a perspective view of the lower die employed in themanufacture of oX-shoes of ordinary shape by my process. Fig. 2 is alikeview of the barof-metal used as ablank in connection therewith. Fig.3 is a plan view of said die with said blank shown in dotted lines inposition for impingement of the upper die. Fig. 4 is a like view of thesame afterthe upper die has performed its office.

Fig. '5 is a plan view of the die used for forgingan oX-shoe withparallel calks, the blank being shown by dotted lines in position forthe operation of the upper die. Fig. 6 is a like view of the same aftersaid upper die has,

impinged upon said blank, and Figs. 7 and 8 are respectively perspectiveviews of blanks after having passed through the dies shown in Figs. 1and 5. j y

Letters of like name and kind refer to like parts in each of thefigures.

In the manufacture of oX-shoes by dies it has heretofore been necessaryto employ a blank which had substantially theform of the finished shoe,which form was given by heating the end of a bar of metal of suitablesize and then bending the sameinto acurved form. The bent position ofthe bar thus employed would, under the action of the dies, haveatendency to resume its original straight form, which tendency wasnotregular, and could not be relied upon, so that it was necessary toemploy iron considerably larger in transverse dimensions than would haveotherwise been required, in order that the die might be completelyfilled each time. To obviate these difficulties, and to materiallylessen the cost of the completed article, is the design of my invention,which invention consists in the method employed forgforging ox-shoe's,whereby a straight heated bar may be used without other preparation,substantially as and for the purpose hereinafter specified.

In the carrying out of my invention, I employ a lower or female die, A,within the upper surface of which is formed a recess, a, thatcorresponds to the general shape of an oX-shoe, and at each end isprovided with deeper recesses a and a, respectively, for the productionof the heel and toe calks of such shoe.

The die A being placed within a drop-press or other equivalent means foroperating dies where it may be subjected to the impingement ofaplain-faced upper die, a plain bar ofmetal, B, is heated and placed uponsaid die A in substantially a line with the transverse centers of thecalk-recesses a and a, as shown by dotted lines of Figs. 3 and 5, afterwhich one or more blows are given by the upper die, and the metal causedto fill the shoe-intaglio. When the bar B is in position for operation,

more of the recess a is upon the outer side of said bar than at theinner side of the same, but the downward and outward inclination of thecentral portion of said recess causes the metalto flow in suchdirection, so as to completely and perfectly fill the space.

By means of myimproved method a saving is effected of from one-seventhto one-sixth in the size and weight of metal used, one heat and onemanipulation is avoided, and one person is enabled to forge and trim ashoe at one heat, when formerly two persons were necessar y and themetal required to be heated twice" in order to accomplish the sameresult.

Having thus fully set forth the nature and merits of my invention, whatI claim is As an improvement in the forging of oxshoes, thehereinbefore-described method, consisting in the placing of astraightbar of heated metal having less width than the finished shoe over theintaglio of an oX-shoe die in substantially a .line with,the transversecenters of the calk-recesses and subjecting the same to one or moreblows by an upper or impinging die, substantially as and for the purposespecified.

In testimony that I claim the foregoing I' have hereunto set my handthis 11th day of August, 1884.

WILLIAM PEARCE.
